HEADREST.

Specification of Letters Patent. i Patented Aug. 10, 1920.A

Applicationv led January 31, 1918. Serial No. 214,653.

T0 all 'whom t may concern: '1 v Be it known that I, MORRIS Lirrs, a citi- Zen of the United States, residing at New York, in the county of New York and State of New York, -have invented certain new and useful Improvements in Headrests, of which the following its a specification.

This invention relates to adjustable head rests for cots, beds,- couches, etc.

One of the objects of the invention isl to provide such a head rest which is simple and cheap to manufacture and lwhich when adjusted will yield readily with the spring above which it is positioned as the weight of a person is placed upon the spring, without danger of the adjustment being lost.

Other objects and aims of ther invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part `specifically referred to in the course of the following de-l scription of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and in which I have shown a merely preferred form of embodiment of the invention, Figure 1 is a perspective view of a form of cot including my invention; Fig. 2 is a plan view of part of a cot or bed frame including a modified form of the invention; Fig. 8 is a sectional view partly in 'elevation taken on the line 3 3 of Fig. 2 looking in the direction of the arrows; and Fig. 4 is a view similar to Fig 3 showing how the head rest of Fig. 1 is secured to the frame.

Referring to the numerals on the drawings, there is shown at 4 the frame of a cot bed having the usual spring 5 extending between angle iron 6 at the ends thereof. About midway of the length of the angle iron 6 at the head of the frame is a prefer.- ably flat bar 7, which has one end secured to the angle iron as by means of a rivet 8, while the bar extends longitudinally of the frame bove the spring, the free end of the bar 7 being depressible. And the upper surface of the free end of the bar 7 carries one or more stop lugs 9,the purpose of which will be hereinafter described. On either side of the bar 7 the angle iron 6 at the head of the frame is provided with apertures 10 in which are accommodated the hooked ends of a crank shaft 11 so that this crank shaft may move about the angle iron as a pivot, toward and from the bar 7. Pivoted on the transverse portion of the crank shaft is a head-rest frame made up preferably of flat end bars l2 riveted to side bars 14 and an intermediate bar 1 5 parallel to the end bars 12 and riveted to the side bars 14. The transverse portion of the crank shaftis pivoted between the bars 12 and .15 and bearing straps 1G rivetedto the respective bars 12 and 15, so that the head-rest frame ma. move pivotally about the crank shaft. The

lower or forward edge of the frame isde-V signed to engage with the stop lugs 9 on the spring bar 7. Vhen not in use the headrest frame lies flat upon the spring 5, the lower or front edge of the frame occupying its position of most forward extension and the transverse part of the crank shaft lying upon the spring bar 7. It will be observed that the side bars 14 of the frame are of suchl length that the frame does not at any time contact with the rigid side members of .the cot frame, but can only come in contact with the spring bar 7 or with the spring 5. The result of this arrangement is that if the weight of a person is placed, as it is in practice, partly upon the head rest and partly upon the bed spring forward of the head rest, the spring bar 7 is depressed as the bed spring is depressed and the head rest maintains its adjusted position, that is to say, is not apt to be disengaged from the forward edge of the head-rest frame.

A modified form of the device is shown in Fig. 2, in which the ends of the crank shaft are journaled in the side pieces of the cot frame as indicated at 10. The head-rest frame in this case is connected to the crank shaft as in Fig. 1, but there is no spring bar 7, and instead of the head-rest frame being held in its adjusted position by its engagement with a spring bar 7, the forward edge portion of the head-rest frame is provided with transverse extensions 17 designed to engage with stop lugs 18 on the upper faces of the horizontally disposed portions of the side angle irons of the cot frame. The operation of this form of the device is in general the same as that of Fig. 1.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the laccompanying drawing shall be interpreted as illustrative and not in a limiting sense.

' vIt is also to be understood that the language used in the following claims is intended to cover all the Vgeneric and specific features of the invention herein. described and all statements of the scope of the inven tion which, asa matter of language, might be said .to fallV therebetween.
